Standardization initiatives are an important part of Anritsu’s research and development activities. We are working to standardize communications protocols through participation in the international standards body ITU-T1 and the next-generation network forum 3GPP.
In mobile phone systems, Anritsu has been involved in determining communications protocols from the earliest stages. As a result, we have provided measuring equipment for the world’s largest number of approved conformance tests of transmission protocols between base stations and mobile handsets.
Manufacturers of mobile handsets and chipsets throughout the world use our measuring instruments to test mobile handsets because handsets that pass are recognized as 3GPP compatible. This contributes to the smooth growth and development of 3G mobile phone systems.
Anritsu continues to conduct similar activities in LTE as well. As Sub-Chair of a protocol conformance testing group, Anritsu is promoting the formulation of protocols for commercial LTE services scheduled to begin in 2010 in Japan and the United States.
For wireline systems, Anritsu has participated in ITU-T for approximately 20 years to promote standardization of jitter and wander2 measurement technologies. Our initiatives have included proposals of measurement technologies for 10Gbit/s, 40Gbit/s and other optical communications systems that have set standards.
Leading global corporations in the telecommunications industry participate in each standards body. Anritsu will continue to use the relationships, knowledge and technologies gained from its aggressive standardization initiatives in product development in order to provide timely, competitive solutions.
Note 1. ITU-T: The International Telecommunication Union (ITU)
Telecommunication Standardization Sector, which sets standards for the telecommunications field as a bureau of the International Telecommunication Union.
Note 2. Jitter and wander:
Defined respectively as short- and long-term variations in signal reception rates in a digital network due to noise or other interference during transmission.
